In October 2015, volunteers flooded an impoverished neighborhood of Bucaramanga in northeast Colombia with thousands of pamphlets promising free houses if Rodolfo Hernandez, a millionnaire engineer, were elected mayor. He won the election, but the free houses never came. Now, Hernandez is running for his country's top job. Despite failing to deliver on his ambitious promise, Hernandez remains popular among many in Bucaramanga, admired for his brashness and for building sports stadiums in poor areas during his 2016-2019 term.
